Specific embodiment
As depicted in figs. 1 and 2, a kind of that seat is detected based on infrared sensor sitting posture including seat body, first group infrared
1, second group of infrared sensor 2 of sensor and system controller 3；Be provided between two preceding chair legs of seat body first group it is red
Outer sensor 1, first group of infrared sensor 1 include several infrared sensors, the arrangement of infrared sensor horizontal homogeneous
Between two preceding chair legs of seat body；Second group of infrared sensor 2 is provided on the chair back of seat body, seat body
System controller 3 is provided with below seat board, second group of infrared sensor 2 includes several infrared sensors, infrared sensing
Device horizontal homogeneous is arranged on the chair back of seat body；The system controller 3 includes processor, loudspeaker, vibrator, nothing
Wire module and power module；The processor respectively with loudspeaker, vibrator, wireless module, power module, first group of infrared biography
Sensor 1, the second infrared sensor 2 are electrically connected.
The present invention is based on the working principles of infrared sensor sitting posture detection seat:
Data Detection is acquired by infrared sensor the present invention is based on infrared sensor sitting posture detection seat and judges current state
Whether take down, if there is prompt keeps correct sitting posture, reads in currently associated parameter, and start system timing；It will acquisition
The controller that obtained data are sent into is analyzed and determined, carries out sitting posture not to judgement, sitting judgement；When controller judgement is current
When state is in sitting, abnormal sitting posture, vibrator, which is started to work, issues different caution signals, and sends current state to remotely
On the computer and cell phone application of monitoring device such as guardian；Children adjust state by different caution signals in time, supervise
It protects people and child's current information state is understood by remote equipment.
A kind of the step of detection method based on infrared sensor sitting posture detection seat, the detection method, is as follows:
(1) sitting posture detection seat judges whether current state is taken by first group of infrared sensor acquisition Data Detection
Under, if taken, processor controls loudspeaker prompt and keeps correct sitting posture, and starts system timing；
(2) as shown in figure 3, detecting that distance of the people back apart from chair back is L by second group of infrared sensori,
Wherein i is each infrared sensor number in second group of infrared sensor；
(3) processor reads in detected people back and chair back distance Li, its variance is sought, calculation formula is as follows:
Wherein, δ1The distance between people back and chair back setup parameter when sitting posture correct for people；
(4) as shown in figure 4, detecting that human body width is W by second group of infrared sensor2And apart from chair on the right side of human body
The distance on back right side is W1, it is W, calculation formula that processor, which calculates the distance between midpoint and right chair leg between two leg of people,
It is as follows:
(5) detect that the distance between two leg of people is X by first group of infrared sensor2And the right leg of people and right chair
The distance between leg is X1, it is X, calculation formula that processor, which calculates the distance between midpoint and right chair leg between two leg of people,
It is as follows:
(6) processor compares the size between W and X, and formula is as follows:
| W-X | < δ2
Wherein, δ2Error setup parameter between two leg spacing centers and gravity center of human body when sitting posture correct for people；
(7) if variance yields DL is greater than δ1Or the difference between W and X is greater than δ2When, processor controls vibrator vibration, prompts
It corrects sitting posture, and processor sends current state to remote supervisory and control(ling) equipment by wireless module；If human body does not carry out correction seat
Appearance, processor continue to control vibrator vibration, and prompt corrects sitting posture, and processor sends current state to remote by wireless module
Range monitoring equipment.
A kind of detection method based on infrared sensor sitting posture detection seat, concrete example calculates as follows:
(1) human error's parameter δ is set1, read in data Li, unit mm:
| Number 1 | Number 2 | Number 3 | Number 4 | Number 5 | Number 6 | Number 7 | Number 8 |
| 88 | 63 | 52 | 52 | 50 | 52 | 65 | 89 |
Cast out number 1 and number 8 takes number 2-7, mean value is
Calculate varianceCompare human error's ginseng
Number δ1With the size between variance D, if variance D be less than human error's parameter δ1, then sitting posture is correct；If variance D is greater than human body
Error parameter δ1, then abnormal sitting posture is true, needs to prompt to correct sitting posture.
(2) human error's parameter δ of constraint condition is set2:
Infrared detection human body width is W2=325 and people distance W of the top half apart from the right chair back1=95
The distance between two leg of people midpoint is calculated apart from right chair leg distance W
Infrared detection goes out the distance between two leg of people X1=375 and people right leg apart from right chair leg distance X2=60
The distance between two leg of people midpoint is calculated apart from right chair leg distance X
Compare human error's parameter δ2With | W-X | between size, if | W-X | calculated value is less than human error's parameter δ2,
Then sitting posture is correct；If | W-X | calculated value is greater than human error's parameter δ2, then abnormal sitting posture is true, needs to prompt to correct sitting posture.
In conclusion the present invention is based on the numbers that infrared sensor sitting posture detection seat is measured by second group of infrared sensor
According to being analyzed and processed, the variance of the data obtained is found out, human body top half sitting posture is judged by the degree of fluctuation of variance, and
The current placement position of people's leg is judged by data that first group of infrared sensor measures, passes through the top half of comparison human body
The central point of central point and two leg spacing away from right side chair side at a distance from, difference comparsion is done, for determining the current sitting posture of people
Situation solves the existing shortage about sitting posture detecting method, keeps correct sitting posture convenient for reminding in real time, forms and practise
It is used.
It is above to describe the preferred embodiment that only innovation and creation provide, it is not intended to limit the invention creation, it is all
Be the invention spirit and principle within change, equivalent replacement etc., should be included in the guarantor of the invention
Within the scope of shield.
